GENERAL DESCRIPTION

The SCOTT Industrial Self-Contained Breathing Apparatus (ISCBA)

is a respirator designed to supply breathable air and respiratory pro-

tection to personnel while performing work in objectionable, oxygen

deficient and/or unbreathable (toxic) atmospheres. Model 2216 ISCBA

respirator uses a 2216 psi cylinder while Model 4500 ISCBA respira-

tor uses a 4500 psi cylinder.

This respirator is to be used only by persons trained in the use of

the respirator and only in conjunction with an organized respiratory

protection program. This respirator is not to be used under water, for

interior structural fire fighting or for any other purpose not authorized

by the organized respiratory protection program that applies specifi-

cally to the user.

The respirator consists of a cylinder and valve assembly for storing

compressed breathing air, a harness and backframe assembly to sup-

port the equipment on the body of the wearer, a single stage pressure

reducer mounted on the backframe, a positive pressure facepiece-

mounted breathing regulator, and a facepiece assembly.

The pressure reducer has an integral bell alarm to warn the user of

diminishing air supply.

The ISCBA respirator is supplied with a steel wire frame fitted with

a waist strap assembly, shoulder straps, and side straps. The straps

are available either in nylon or flame resistant Kevlar1 material.

The breathing regulator is equipped with an air saver/donning switch

which can be activated to prevent rapid loss of air supply if the sys-

tem is turned on prior to donning the facepiece or if the facepiece is

removed while the cylinder valve is open. Respirators are available

with or without a quick disconnect in the hose to the mask-mounted

breathing regulator.

The facepiece utilized on this respirator is available in a variety of

sizes and configurations for standard use or special applications. The

facepiece may be readily detached from the breathing regulator to

allow for utilization of the best fitting and most comfortable size face-

piece for an individual user. Fit testing per OSHA Standard 29 CFR

Part 1910 or ANSI Standard Z88.2 requires testing in the negative

pressure mode using equipment such as a Portacount Plus2 Respira-

tor Fit Tester. For this, SCOTT facepieces require use of SCOTT Fit

Test Adapter P/N 804057-01 or equivalent and appropriate negative

pressure testing equipment. Mask Seal Kit P/N 805655-01 may also

be required to attain a proper fit. Head harnesses are available in

several materials including polyester and Kevlar1. Each size facepiece

may be equipped with a lens kit if the use of corrective spectacles is

required. See ACCESSORIES Section for facepiece options.

The duration of the respirator may be extended by use of a low pres-

sure airline air supply. (For details see ACCESSORIES Section.) The

respirators are National Institute for Occupational Safety and Health

(NIOSH) approved for use in temperatures to -25 °F / -32 °C.

Depending on the cylinder and valve used, the respirators are ap-

proved and maintained under NIOSH approval numbers listed on the

NIOSH APPROVAL LABEL. These respirators meet the requirements

of Title 42, Part 84 of the Code of Federal Regulations when used

and maintained in accordance with these instructions and the NIOSH

label located on the harness and backframe assemblies. A complete

NIOSH APPROVAL LABEL is included with these instructions.

FACEPIECE FITTING AND FIT TESTING

A respirator Quantitative Fit Test must be performed to ensure the correct

respirator facepiece size has been selected and assigned to the user. It is

the responsibility of the Respiratory Protection Program Manager or Safety

Coordinator to assist the user in selecting the correct respirator size relative

to the user’s facial features and dimensions. Fit Testing must be performed

with any approved SCOTT accessories that will be used with the respirator

installed, such as a communications device installed on the facepiece.

Respirator fit tests are explained fully in the American National Standard

Practices for Respiratory Protection, ANSI Z88.10-2001 which is published

by the American National Standards Institute (ANSI), 11 West 42nd Street,

New York, New York, 10036, and in the Occupational Safety and Health

Standards, OSHA 29 CFR 1910.134 Appendix A, which is published by the

Occupational Safety and Health Administration (OSHA), 200 Constitution

Avenue, NW, Washington DC, 20210.

Quantitative Fit Testing per OSHA Standard 29 CFR Part 1910.134 Appendix A,

or ANSI Standard Z88.10-2001 requires testing in the negative pressure mode

using equipment such as a Portacount 1 Respirator Fit Tester. For Quantitative

Fit Testing, SCOTT facepieces require use of the appropriate negative pres-

sure testing equipment such as the Portacount Respirator Fit Tester along

with the following:

• SCOTT 40mm facepiece Adapter, P/N 200423-01,

• a new SCOTT P100 Cartridge, P/N 052683,

• SCOTT Probed Fit Test Adapter P/N 805628-01 or equivalent probed

facepieces and the full range of sizes and styles

• Mask Seal Kit, P/N 805655-01

• the appropriate SCOTT communication device and mounting bracket

properly installed on the facepiece, if such an accessory will be used

with the respirator.

• any other optional hood, eyeglass, or other accessory that will be used

with the respirator.

The size and style facepiece must be selected based on the user’s measured

face size. For initial fitting, carefully don the facepiece and conduct a NEGA-

TIVE PRESSURE LEAK TEST according to the instructions provided with the

40mm Adapter. Refer to the DONNING PROCEDURE section of this instruc-

tion for the procedure. Follow the DONNING PROCEDURE CAREFULLY. If

the selected facepiece does not pass the NEGATIVE PRESSURE LEAK TEST

or does not fit securely without movement in the chin or chin cup area or the

user experiences discomfort in the chin or throat, try the next nearest size,

larger or smaller. After passing the NEGATIVE PRESSURE LEAK TEST, the

facepiece size selected must be verified by successfully passing a respirator

Quantitative Fit Test.

When fit testing for Open-Circuit, Pressure Demand Self-Contained Breathing

Apparatus and/or Type C Pressure-Demand Supplied Air Respirator mode

of operation (minimum Fit Factor equal to or greater than 500 minimum)

appropriate negative pressure testing equipment must be used. You should

use a P100 Filter, SCOTT P/N 052683 and the SCOTT P/N 805628-01 Fit

Test Adapter.

When using a Portacount Respirator Fit Tester for Quantitative Fit Testing, TSI

recommends that the level of particles in the ambient air must be between

5000 and 30000 particles/cm3. Refer to the Portacount Respirator Fit Tester

user instructions for details including available Particle Generators to use

with the Portacount Respirator Fit Tester if you have difficulty achieving the

minimum level of ambient particle count required.

Test subjects must be in good health at the time of the fit testing. Smoking

or eating less than 30 minutes prior to the test is prohibited. Any and all

conditions that might interfere with a good face to facepiece seal must be

addressed and corrected before performing the fit testing. Refer to the list of

conditions in the DONNING PROCEDURES section of this instruction.

WARNING

Page 5 of 32 P/N 89332-01 Rev F 7/11

To verify the fit factor of the respirator, testing must incorporate an exercise

regimen of normal daily activities. SCOTT requires the following set of fit

test exercises, which are based on OSHA Standard 29 CFR Part 1910.134

Appendix A, and ANSI Z88.10-2001 with modifications.

Exercises are to be performed each for 60 seconds (except as noted) in a

standing position during the test:

• Normal Breathing

• Deep breathing

• Turning head side to side

• Moving head up and down (look up/look down)

• Talking (read the Rainbow Passage)

• Grimace (15 seconds)

• Bending Over (touch toes) / Reach up (toward the ceiling)

• Normal Breathing (repeat)

Fit test exercises must be performed carefully as if the respirator was be-

ing used in a hazardous atmosphere. DO NOT bump the facepiece, filter,

or adapter into the body through exaggerated motions. DO NOT talk except

when directed to by the test administrator.

SCOTT requires that users of this respirator with an approved SCOTT face-

piece, must achieve a Fit Factor of at least 500 for Type C Pressure-Demand

Supplied Air Respirator mode of operation for use with their assigned face-

piece style and size using the fit test procedures and exercise regimen stated

above. If a Fit Factor of at least 500 cannot be achieved with any facepiece

size or style, the user MUST NOT use this respirator.

If the respirator user passes a NEGATIVE PRESSURE LEAK TEST but

DOES NOT pass a respirator Quantitative Fit Test, try the next nearest size,

larger or smaller and repeat the NEGATIVE PRESSURE LEAK TEST and

the Quantitative Fit Test. If leakage is still detected, either per these user

instructions or the OSHA fit testing process, the use of Mask Seal Kit P/N

805655-01 may be required to attain a proper fit. Refer to the INSTALLATION

AND USE INSTRUCTIONS, SCOTT P/N 89462-01, included with the Mask

Seal Kit. After installing the Mask Seal Kit, repeat the fit testing process to

confirm a proper fit.

Once the proper size is selected and assigned to the user following suc-

cessful Portacount Respirator Fit Tester testing to achieve minimum Fit

Factors required, the respirator user must perform and pass a NEGATIVE

PRESSURE LEAK TEST as described in these instructions every time the

facepiece is donned to ensure proper fit before using the respirator in a

hazardous atmosphere.

During NEGATIVE PRESSURE LEAK TESTING, any facepiece leakage that

is detected from other than the face to facepiece seal may indicate damaged

or defective equipment. Remove the defective equipment from service and

tag for repair by authorized personnel. Repeat the testing with equipment

known to be operating properly.

IF A SATISFACTORY NEGATIVE PRESSURE LEAK TEST CANNOT BE PER-

FORMED, DO NOT USE THE RESPIRATOR OR ENTER THE HAZARDOUS

ATMOSPHERE.

The facepiece alone does not provide any protection against a hazardous

atmosphere without the use of the complete respirator.

A respirator Quantitative Fit Test must be routinely carried out as outlined

above for each user of this respirator to determine or confirm the amount of

protection that the respirator provides.

Periodically repeating the fit testing is required to identify any physical

changes of the user (such as those listed in the DONNING PROCEDURES)

which could effect the fit of the facepiece.

WARNING

FAILURE TO PROPERLY FIT THE

RESPIRATOR FACEPIECE TO THE USER MAY

RESULT IN LITTLE OR NO RESPIRATORY

PROTECTION AND MAY EXPOSE THE

WEARER TO SUBSTANCES WHICH CAN

CAUSE SERIOUS INJURY OR DEATH.

WARNING

THE RESPIRATOR USER MUST

IMMEDIATELY LEAVE THE AREA

REQUIRING RESPIRATORY PROTECTION

WHEN THE BELL END OF SERVICE

INDICATOR ALARM ACTUATES.

ACTUATION OF THE BELL END OF

SERVICE INDICATOR ALARM WARNS

THAT APPROXIMATELY 25% OF FULL

PRESSURE REMAINS IN THE AIR SUPPLY

CYLINDER (THAT IS, APPROXIMATELY

3/4 OF THE TOTAL AIR SUPPLY HAS

BEEN USED). A DELAY IN LEAVING THE

AREA AFTER ALARM ACTUATION MAY

RESULT IN INJURY OR DEATH.

WARNING

THE RESPIRATORY PROTECTION PROGRAM

UNDER WHICH THIS EQUIPMENT IS TO BE

USED MUST DETERMINE THE APPROPRIATE

LEVEL OF PROTECTION THAT THE

RESPIRATOR IS EXPECTED TO PROVIDE.

USE OF INAPPROPRIATE RESPIRATOR

EQUIPMENT FOR THE WORK ENVIRONMENT

MAY RESULT IN EXPOSURE TO THE

HAZARDOUS ATMOSPHERE WHICH MAY

CAUSE SERIOUS INJURY OR DEATH.

CHOOSING THE APPROPRIATE EQUIPMENT

Respirators reduce but do not eliminate all exposure to the hazardous at-

mosphere. Some facepiece/respirator combinations are more effective than

others at reducing exposure depending on the nature and the concentration

of the contaminant in the hazardous atmosphere. When choosing a respirator

and facepiece, the respiratory protection program under which this respira-

tor is to be used must determine the appropriate level of protection that the

facepiece/respirator is expected to provide. Use of inappropriate RESPIRA-

TOR equipment for the work environment may result in exposure to the

hazardous atmosphere which may cause serious injury or death.

The respiratory protection program must also take into consideration the levels

of exposure which may be hazardous irrespective of respiratory protection

(e.g.: contaminants which are toxic through exposure to unprotected skin).

Additional protective equipment such as apparel may be required. However,

any additional protective equipment must not interfere with access to or op-

eration of the respirator.

When properly donned and operated, the SCOTT ISCBA respirator provides

limited protection from airborne contaminants to only the respiratory system

and part of the face of the user. The using agency must provide the appro-

priate protective clothing for use with the ISCBA respirator and must insure

that protective clothing does not interfere with the operation of the ISCBA

respirator.

SERVICE LIFE

The 2216 ISCBA respirator is rated and approved by NIOSH as a 30 min-

ute duration unit and the 4500 ISCBA respirator is rated and approved by

NIOSH as a 30 minute / 45 minute / 60 minute duration unit (depending on

capacity of cylinder used) when properly donned, used and maintained by

trained personnel. A bell alarm actuates when approximately 25% of

the rated service time remains. The alarm will continue to operate

until the cylinder is nearly depleted.

The user should not expect to obtain exactly the rated service life from this

respirator on each use. The work being performed may be more or less

strenuous than that used in the NIOSH test. Where work is more strenuous,

the duration may be shorter, possibly as short as one-half the rated service

time. Likewise, the time remaining after the bell alarm actuates will be simi-

larly reduced.

The duration of the respirator will depend on such factors as:

1. the degree of physical activity of the user;

2. the physical condition of the user;

3. the degree to which the user’s breathing is affected by excitement, fear

or other emotional factors;

4. the degree of training or experience which the user has with this or similar

equipment;

5. whether or not the cylinder is fully charged at the start of the work period;

6. the possible presence in the compressed air of carbon dioxide concentra-

tions greater than .04% normally found in atmospheric air;

7. the atmospheric pressure; for example, if used in a pressurized tunnel

or caisson at 2 atmospheres (15 psi gauge) the duration will be one-half

as long as when used at 1 atmosphere; and at 3 atmospheres will be

one-third as long;

8. loose or improperly fitting facepiece;

9. the condition of the respirator being used.

WARNING

THIS RESPIRATOR PROVIDES PROTECTION

ONLY TO THE USER’S RESPIRATORY

SYSTEM AND TO PART OF THE FACE.

IF THE HAZARDOUS ATMOSPHERE

CONTAINS TOXINS OR CONTAMINANTS

WHICH MAY POISON THROUGH THE SKIN,

ADDITIONAL PROTECTIVE EQUIPMENT

MAY BE REQUIRED. FAILURE TO PROVIDE

ADEQUATE PROTECTIVE EQUIPMENT FOR

THE HAZARDS IN THE WORKPLACE MAY

RESULT IN SERIOUS INJURY OR DEATH.

INSPECTION OF THE BREATHING AIR CYLINDER

1. Visually inspect breathing air cylinder and valve assembly for

physical damage such as dents or gouges in metal or in composite

wrapping. Cylinders which show physical damage or exposure to

high heat or flame, such as paint turned brown or black, decals

charred or missing, pressure gauge lens melted or elastomeric

bumper distorted, and cylinders which show evidence of exposure

to chemicals such as discoloration, cracks in the cylinder or the

composite wrapping, peeling of the outer layers of the composite

wrapping and/or bulging of the cylinder wall, shall be removed

from service and emptied of compressed air. Publications on

compressed gas cylinder inspection procedures are available from

Compressed Gas Association Inc., 1725 Jefferson Davis Hwy.,

Suite 1004, Arlington, VA 22202 (703-412-0900).

2. Check the latest cylinder hydrostatic test date to ensure it is cur-

rent. The date of manufacture marked on the cylinder is also the

date of the first hydrostatic test. All breathing air cylinders used

with SCOTT AIR-PAK SCBA’s must be visually inspected regularly

and hydrostatically tested at the required intervals by a licensed

cylinder retester. Intervals for hydrostatic testing are established in

the appropriate US Department of Transportation (DOT) specifica-

tion or applicable DOT exemption, or in the appropriate Transport

Canada (TC) Permit of Equivalent Level of Safety. Refer to the

current revision of Safety Precautions for AIR-PAK Cylinders,

SCOTT P/N 89080-01, available on request from SCOTT Safety.

Composite fiber overwrapped cylinders must be tested up to

their maximum life which, at the time of the publication of this

instruction, is 15 years from the date of manufacture. It is the

responsibility of your organized respiratory protection program to

arrange for visual inspection and hydrostatic testing of cylinders

by a licensed retester.

3. Check for damage of the cylinder valve hand wheel and the

threads on the cylinder valve outlet.

4. Check the relief valve (burst disc) for damage or dirt.

5. Check the cylinder pressure gauge for “FULL” indication. If cyl-

inder pressure is less than “FULL,” replace with a fully charged

cylinder.

Proceed to INSPECTION OF THE RESPIRATOR

REGULAR OPERATIONAL INSPECTION

The following procedure shall be used when you first receive the

respirator and for regular inspection of the respirator. Respirators main-

tained for emergency use must be inspected as frequently as required

to assure the respirator will function properly when required. The US

Labor Department (OSHA), pursuant to 29 CFR 1910.134, requires at

least monthly inspection of respirators maintained for emergency use.

NIOSH recommends an inspection for cylinder pressure at least weekly.

All respirators shall be inspected after each use. If any damage or

malfunction is noted, remove the respirator from service and tag for

repair by authorized personnel.

IF ANY DISCREPANCY OR MALFUNCTION IS NOTED DURING

THE INSPECTION, DO NOT USE THE RESPIRATOR. REMOVE

THE RESPIRATOR FROM SERVICE AND TAG IT FOR REPAIR

BY AUTHORIZED PERSONNEL.

PREPARATION FOR USE

DONNING THE ISCBA RESPIRATOR

1. Always check the cylinder gauge for a “FULL” indication. If the cyl-

inder is not full, replace the cylinder before use. A gauge indication

of other than full may indicate an air leak in the cylinder and valve

assembly or a malfunction of the gauge assembly.

2. Always verify that the cylinder is held securely by the cylinder reten-

tion assembly.

3. If the respirator is stored in a hard or soft storage case:

a) Place the case on the ground or level surface and open the

case.

b) Stand the respirator on the cylinder valve with cylinder toward you

and the shoulder straps away from you.

c) Grasp both shoulder pads, one in each hand.

d) Pick up the respirator and swing it around behind you.

e) Release your grasp while sliding your arms under the shoulder

pads. Ensure that the shoulder pads fall into place on the shoul-

ders.

f) While leaning slightly forward, pull down on the shoulder straps

to adjust the harness to fit your body.

4. If a wall storage bracket is used, follow the instructions of the bracket

manufacturer for placing arms through shoulder straps and freeing

the respirator from the bracket.

a) Ensure that the shoulder pads fall into place on the shoulders.

b) While leaning slightly forward, pull down on the shoulder straps

to adjust the harness to fit your body.

5. While still leaning slightly forward, connect the waist belt buckle and

adjust the belt by pulling forward on the two (2) side-mounted belt

ends. Tuck the belt ends into the waistband.

6. Stand up straight and readjust the shoulder straps as needed to

ensure the weight of the backframe is carried on the hips. Tuck the

shoulder strap ends under the shoulder straps.

7. Fully depress the center of the air saver/donning switch on top of

regulator and release.

8. If the regulator is not attached to the facepiece, proceed as fol-

lows:

a) Verify that the regulator gasket is not damaged and is in place

around the outlet port of the regulator.

b) Align the two flats of the regulator outlet port with the correspond-

ing flats in the facepiece port (the red purge valve on the regula-

tor will be in the 12 o’clock position). Insert the regulator into the

facepiece port.

c) Rotate the regulator counterclockwise (as viewed from inside of

facepiece) until the red purge valve knob is on the left side of the

facepiece. The lock tab on the regulator will lock into the facepiece

retainer with a “click.” When the lock tab is properly engaged, the

regulator will not rotate.

USE OF THE RESPIRATOR

The following information provides the basic steps for use of the

ISCBA respirator. Training and practice with the equipment are re-

quired before use to assure that the user is completely familiar with

the operation of the respirator.

The ISCBA respirator is typically worn over most protective garments,

but may be worn under encapsulating protective garments such as

haz-mat suits. Determine what other protective gear will be used and

don the ISCBA respirator and the facepiece accordingly.

If respirator use is expected at temperatures near or below freezing,

or if respirator is to be used after being kept at temperatures near or

below freezing, refer to LOW TEMPERATURE OPERATION Section

for additional information and supplemental procedures.

procedures for donning, use, and termination of use. The user must

be familiar with and practice the prescribed donning, leak test, use,

and termination of use procedures prior to respirator use. Follow the

donning instructions for the model facepiece you have.

The DONNING INSTRUCTIONS for FOUR STRAP full facepieces

(such as the AV-2000, AV-3000, Scott-O-Vista, and the Weld-O-Vista)

and the FIVE STRAP full facepieces (such as the AV-3000 SureSeal)

are included in this instruction.

The respirator MUST NOT be worn when conditions prevent a good

face to facepiece seal. Such conditions include but are not limited

to:

• long hair at the forehead or the side of the face that interferes with

the sealing surface or gets caught in the head harness buckles,

• facial hair such as growth of beard or sideburns, or low hairline

that crosses or interferes with the sealing surface,

• thick or protruding hairstyles such as pony tails or buns that in-

terfere with the smooth and close fit of the head harness to the

head,

• temple pieces on corrective glasses,

• a skull cap that projects under the facepiece,

• excessive use of cosmetics including moisturizers, make-up, or

after shave,

• the absence of one or both dentures,

• weight loss or weight gain since last fit testing,

• facial scarring,

• anything else which interferes with the face to facepiece seal or

the fit of the head harness to the head.

Periodically repeating the fit testing is required to identify any physical

changes of the user (such as those listed above) which could affect

the fit of the facepiece.

DONNING PROBLEMS

1. Perform a personal check of the Facepiece and Head Harness

and address any donning problems. OSHA standard 29 CFR

1910.134 requires teams of at least two people for situations

where this type of equipment is used. Have your partner help

you verify the facepiece is donned properly.

Possible problems include:

a) Head Harness Strap twisted,

b) Head Harness off-center or not flat against the head,

c) Head Harness too high on the head,

d) Hair or clothing in the face seal,

e) Face seal rolled over inside the facepiece rather than flat

against the face

f) Facepiece is sitting too low on the face as evidenced by pres-

sure on the forehead or the facepiece making contact with the

throat area permitting a break in the seal.

The illustrations below depict the AV-3000 SureSeal, but similar

conditions can occur with the AV-2000 or AV-3000 facepiece as

well.

If any donning problems are found, remove the facepiece and

re-don the facepiece correctly.

2. Proceed to BEGIN USE OF THE RESPIRATOR as instructed

below.

BEGIN USE OF THE RESPIRATOR

WARNING

WHEN THE BELL ALARM ACTUATES IT

WARNS THE USER THAT APPROXIMATELY

25% OF THE FULL PRESSURE REMAINS IN

THE CYLINDER (THAT IS, APPROXIMATELY

3/4 OF THE TOTAL AIR SUPPLY HAS

BEEN USED). IN THIS EVENT, LEAVE THE

CONTAMINATED AREA AT ONCE. IN AREAS

WHERE MORE THAN ONE RESPIRATOR IS

BEING USED, YOU MAY IDENTIFY YOUR

OWN ALARM BY SENSING THE VIBRATIONS

THROUGH YOUR BACKFRAME.

1. If regulator is not attached to facepiece, be sure the regulator

gasket is in place around the outlet port of the regulator and not

damaged.

2. To attach the regulator to the facepiece, hold the regulator with

the red purge valve in the 12 o’clock position, align the two flats

of the outlet port with corresponding flats in the facepiece port

and insert. Rotate the regulator counterclockwise (viewed from

inside of facepiece) so that the red purge valve knob is situated on

the left side of the facepiece. The lock tab on the mask-mounted

regulator will lock into the facepiece retainer with a “click”. When

properly engaged, the regulator will not rotate.

With facepiece sealed to face, inhale sharply to actuate respirator.

Air will then be supplied during inhalation.

NOTE

IF AIR IS NOT SUPPLIED ON FIRST INHALATION, CHECK THAT

CYLINDER VALVE IS OPEN, REMOTE GAUGE INDICATES PRES-

SURE IN CYLINDER AND FACEPIECE IS SEALED TO FACE.

3. NEGATIVE PRESSURE LEAK TEST – Close cylinder valve by

simultaneously pushing in on cylinder valve knob and rotating it

clockwise. Breathe on respirator until airflow stops. The bell alarm

will actuate, then stop. Inhale slowly and hold your breath mo-

mentarily. No leakage of air shall be detected and the facepiece

shall be drawn slightly to the face. Open cylinder valve fully and

breathe normally.

4. If the environment is suitably quiet, leakage from the facepiece

can also be detected by listening for a flow of air while holding

your breath. Inhale and hold your breath momentarily after don-

ning the facepiece. Do not depress air saver switch. Air should

not be heard flowing into the facepiece from the regulator and no

flow of air shall be detected outward from the facepiece.

NOTE

IF LEAKAGE OF AIR IS DETECTED DURING EITHER OF THE

ABOVE PROCEDURES, DEPRESS THE AIR SAVER/DONNING

SWITCH ON THE TOP OF THE REGULATOR, DOFF THE FACE-

PIECE AND REPEAT DONNING STEPS 1 THROUGH 8 ABOVE.

IF LEAKAGE PERSISTS, DO NOT USE THE RESPIRATOR.

5. Proceed with use of respirator in accordance with your respiratory

protection program.

EVERY ENTRY INTO A CONTAMINATED OR UNKNOWN ATMO-

SPHERE SHOULD BE PLANNED TO ENSURE THAT THERE IS

SUFFICIENT AIR SUPPLY TO ENTER, CARRY OUT THE TASKS

REQUIRED AND RETURN TO A SAFE BREATHING AREA. THE

USER SHOULD CHECK THE REMOTE READING PRESSURE

GAUGE ON THE SHOULDER STRAP PERIODICALLY TO DE-

TERMINE THE RATE OF AIR CONSUMPTION. IN ANY EVENT,

THE USER MUST BE CERTAIN TO ALLOW SUFFICIENT AIR

FOR EGRESS FROM THE CONTAMINATED AREA. IF ENTRY

IS ATTEMPTED AFTER THE AIR HAS BEEN PARTIALLY CON-

SUMED (CYLINDER LESS THAN FULL), THE USER MUST BE

CERTAIN THAT THE REMAINING AIR WILL BE SUFFICIENT FOR

SAFETY.

Leave the contaminated or unknown atmosphere immediately

if the bell alarm actuates and, in a safe area, determine cause

of alarm. When air supply has been depleted, replace cylinder

following CYLINDER REPLACEMENT PROCEDURE.
